2050 Ultra Flood Plain in Ayutthaya, Thailand by Shma Company Limited

The goal of modern development has created a clear separation between agricultural and industrial activities, between human and nature, between fluid and solid territories, which become a threat to human living. As we move forwards and slowly detach from nature, we neglect the power of it and forget how we once live with it. Ayutthaya is the city which illustrates such on-going situation clearly, from the day when water was city’s breath to the day when water become city’s catastrophe to local economy, society and environment. In planning for the prospect Ayutthaya we shall try to understand the formation of crisis, in order to determine the new balance between water, Ayutthaya living and Chao Phraya river basin.

1350 : Flood city

Back in the 1350s, Ayutthaya was the capital city of Thailand and truly called the water city. Since the beginning of the era Ayutthaya always flood during the rainy season. People learn to live and adapt with the water. The benefits of the water cause people to change the way they live including their economic and cultural activities to connect with the water.

1967 : Flood blocking city

The evolution of the city cause Ayutthaya to developed in the wrong direction. The influence of green revolution in 1967 (which allow farmer to use irrigation instead of natural water source) and economic development direction caused the development that set Ayutthaya’s fluid and solid territories apart.

2011 SHIFT : Flood Choke City

We have witnessed 36,000 million cu.m. of water surge into the lower Chao Phraya Flood Plain and damage Ayutthaya tremendously beyond the historical records, especially for the unplanned settlement in urban area and industrial estates that were built in water way. The damage cost 1.2 billion baht with more than 200,000 lives unemployed. Ironically, agricultural land or natural water detention area could not take in water as they were still harvesting. This year flood surely triggered Thai society to revise our urban planning, economic production activities and our way of living to suitably fit with the nature

2050 Between people and water

Flood as Natural Capital

The main idea is to look at nature not just a resource but a natural capital that needs to be maintained as much as physical or human capital. In the context of Ayutthaya, we need to look at the abundance of water not a threat but an economic opportunity.

Water Detention Network

All agricultural area is the main key to the effective water management for Ayutthaya and Chao Phraya river basin. Through extending the potential of flood plain characteristic and the existing irrigation system (which covers 70% of area), the elements are transformed into the “water detention network system”.

Moving from separation between industry and agriculture, between human and nature, between fluid and solid territories, towards the new development on the same level field where agriculture and industry assist one another, driven by water-related activities 1,255,629 rai of agricultural land or 78% of Ayutthaya total area are transformed to agricultural++ land to perform not only rice production but also fulfill and enhance every dimension of the city and prepare it for the future challenge.

Agricultural land are developed into 5 roles

Agriculture + Water Infrastructure

Rearrange Ayutthaya land typography in managing flood, waste water and drought of Chao Phraya Flood plain.

Agriculture + Food

Floating agriculture during the flood period so Ayutthaya can grown food all year round

Agriculture + Energy & Waste Exchange

becoming self-sustain province, Ayutthaya will harvest energy from their own agriculture waste.

Agriculture + Industry

Promoting Ayutthaya as agri-industrial city as well as the South-East Asia logistic hub

Agriculture + Tourism

Using Ayutthaya unique natural and cultural landscape condition to attract more tourist throughout the year

Design : Agricultural land are developed into 5 roles following:

1. Agriculture + Water Infrastructure: Water detention reservoirs, the agricultural and management of His Majesty the King with the ratio of 30:30:30:10 (Rice field:Plant:Water Infrastructure:Settlement) will serve as effective tools to store large amount of water in flood season for consumption in the dry season. Agricultural area can be turned into large Water detention areas by simply increasing the height of the existing polder. When raised, these ridges can help the flood plain to hold more of water in 200 years amount. Each pixel of land has drain channel which bio-filtrates this water before it is released to the river

2. Agriculture + Food: In order to convert agricultural land into water detention area during the flood season, farming practice has to be adjusted. The current practice of In-Season Rice Field should be no longer encouraged since this method has an overlap season with the flood. During the flood season, the land are still being use to grow rice, thus, cannot be used to store water. On the other hand, another method of farming called Double-Cropped Field will leave these lands open for water detention.

3. Agriculture + Energy & Waste Exchange: Organic waste of agricultural lands in Ayutthaya is capable for creating electricity for the local area by Gasification process that will convert waste into electricity without releasing any CO2(research in biomass). Electricity generated is sufficient to be used by everyone and even left over for trade. The waste from urban area can composting and transform into fertilizer. Recycled waste from factories can be used to build polder in agricultural area, by Landfill. These exchanges of benefits will strengthen the relationship between agricultural and industrial sectors.

4. Agriculture + Industry: Creating an economic corridor connecting North to South, Dwai(Myanma) to Kanchanaburi(Thailand) and Bangkok to Ho Chi Min City(Vietnam). The building of a high-speed train will convert Ayutthaya into a logistic hub of the region. Ayutthaya will see influx of goods, labor, investment, and other economic activities. This is equipped the town with an ability to increase its agriculture productivity. Cheap agriculture products can be import from the neighboring countries and to be manufactured, processed, and value-added with more material variety.

5. Agriculture + Tourism: The high-speed train and the forming of AEC will bring tourists into the city. At the same time, Ayutthaya still preserve its famous world heritage sites of the ancient city and distribute visitors to surrounding area outside “old town” The new tourism development must consider values of the city’s agricultural tradition, local environment, and technology. Moreover flooding can create a water based activity and attraction during 4 month floating tent time

Ayutthaya is one of the 8 cities in the lower Chao Phraya Flood Plain, which are facing development challenge and water management. If flood plain become water detention network and harvest ‘Natural Capital’, not only the entire flood plain will benefit from better management of water, but also apprising the area value both economically and culturally.

Exhibition : Architect Expo 2012, took place in Mueng Thong Thani, Thailand. In response to the flood situation that happened in Thailand last year. This year, Shma participated in the “water brick” exhibition held by the Association of Siamese Architects.

The conceptual model represents our solution for flooding situation. Dividing into 5 cities base on agricultural idea, these cities response to the idea of sustainable and add value to its own city. From the small network working together to the big scale. Each city can create and organize its own waste and energy, food,water infrastructure, tourists and products.

Each city represents by the pattern which explain the process of each one. The section graphic near the pattern also give a clear explanation to each city. The conceptual model was made to different pixel shape. Each one surround by polder that use as a detention. The plant that surround the pixel create the energy

The settlement of the cities are represented in different squares which varies in shapes and sizes. The diversity of the urban and agricultural forms different viewing experiences . Each square represents as the old and new city.

The exhibition was well received by the public. The model interacts and communicates with the public viewers through conceptual texture. The lighting effect which contrasts with the white model adds up to the whole viewing experience. The animation that present nearby is an animation that show the process from the research to the design solution.
